1.
Which ASTM standard governs the qualification of concrete testing
technicians at an advanced level?
A. ASTM C31
B. ASTM C94
C. ASTM C1077
D. ASTM C39
Answer: C
ASTM C1077 establishes minimum technical requirements for
laboratory and field personnel, aligning with Level IV responsibilities.
2.
For a Level IV technician overseeing multiple labs, which is the most
critical duty under ASTM C1077?
A. Performing all compressive strength tests personally
B. Maintaining documented training and competency evaluations
C. Supervising fresh concrete sampling only
D. Approving mix designs once per year
,Answer: B
Level IV requires personnel competency programs with documented
evaluations.
3.
A concrete mixture requires strict control of alkali–silica reactivity
(ASR). Which test is most appropriate to evaluate mitigation
effectiveness?
A. ASTM C1260
B. ASTM C173
C. ASTM C138
D. ASTM C617
Answer: A
C1260 is the accelerated mortar bar test for ASR potential.
4.
When verifying the traceability of calibration for testing equipment,
the Level IV technician must ensure calibration follows standards
traceable to:
A. ASTM technical committees
B. The National Institute of Standards and Technology (NIST)
C. Local concrete suppliers
D. NICET board recommendations
Answer: B
Calibration traceability must connect to national metrology standards
such as NIST.
,5.
Which best describes a robust Quality Management System (QMS) for
a concrete testing laboratory?
A. A collection of equipment calibration sheets
B. Procedures, internal audits, training, and documentation aligned to
ASTM C1077
C. A schedule for compressive testing only
D. Annual technician meetings
Answer: B
A comprehensive QMS includes procedures, audits, training, and
documentation.
6.
A high-performance concrete mix uses silica fume. What primary
adjustment is typically required?
A. Increase coarse aggregate size
B. Increase mixing time
C. Reduce air content target
D. Lower cement replacement percentage
Answer: B
Silica fume requires extended mixing to ensure dispersion.
7.
During an audit, a lab is found to have several technicians performing
density tests without current certification. The Level IV response should
be:
A. Retrain only one technician
, B. Suspend all density testing until compliance is restored
C. Continue testing but submit a corrective plan later
D. Reduce frequency of density testing
Answer: B
Non-certified personnel performing tests is a major nonconformance
requiring immediate corrective action.
8.
Which property does ASTM C143 measure?
A. Air content
B. Unit weight
C. Slump
D. Temperature
Answer: C
ASTM C143 is the slump test.
9.
A concrete mixture has extremely high early strength demands. Which
cement type is most appropriate?
A. Type I
B. Type II
C. Type III
D. Type IV
Answer: C
Type III cement is used for high early strength.
